יַכְּכָ֣ה יְ֠הוָה בַּשַּׁחֶ֨פֶת וּבַקַּדַּ֜חַת וּבַדַּלֶּ֗קֶת וּבַֽחַרְחֻר֙ וּבַחֶ֔רֶב וּבַשִּׁדָּפ֖וֹן וּבַיֵּרָק֑וֹן וּרְדָפ֖וּךָ עַ֥ד אָבְדֶֽךָ׃
גאָט װעט דיך פּלאָגן מיט דער, און מיט קדחת, און מיט היץ, און מיט ברענונג, און מיט טריקעניש, און מיט קאָרנבראַנד, און מיט װעלקעניש; און זײ װעלן דיך נאָכיאָגן ביז דו װעסט אונטערגײן.
Mishneh Torah, Fasts
About blight and about chlorosis, from when it begins in the produce. And we decree a fast about it and sound [trumpets] even if it only began in a small place, like the fill of the opening of an oven.
Mishneh Torah, Fasts
About sicknesses — how is this? See that [if] a sickness came down upon many people in one city — such as diphtheria or violent fever and that which is similar to them — and they were dying from this sickness, it is surely a communal trouble. So we decree a fast for it and sound [trumpets]. And likewise do we fast and sound [trumpets] for damp scabs (chikhukh). But we only cry out for dry scabs.
